NAME
     rbash - restricted bash, see bash(1)

SYNOPSIS
     rbash

RESTRICTED SHELL
     If bash is started with the name rbash, or the -r option  is
     supplied  at  invocation,  the  shell becomes restricted.  A
     restricted shell is used to set up an environment more  con-
     trolled  than the standard shell.  It behaves identically to
     bash with the exception that the following are disallowed or
     not performed:

     +o    changing directories with cd

     +o    setting or unsetting the values of SHELL, PATH, ENV, or
          BASH_ENV

     +o    specifying command names containing /

     +o    specifying a file name containing a / as an argument to
          the . builtin command

     +o    Specifying a filename containing a slash as an argument
          to the -p option to the hash builtin command

     +o    importing function definitions from the shell  environ-
          ment at startup

     +o    parsing the value of SHELLOPTS from the shell  environ-
          ment at startup

     +o    redirecting output using the >, >|, <>, >&, &>, and  >>
          redirection operators

     +o    using the exec builtin command  to  replace  the  shell
          with another command

     +o    adding or deleting builtin commands with the -f and  -d
          options to the enable builtin command

     +o    Using the enable builtin  command  to  enable  disabled
          shell builtins

     +o    specifying the -p option to the command builtin command

     +o    turning off restricted mode with set +r or set +o  res-
          tricted.

     These restrictions are enforced after any startup files  are
     read.

     When a command that is found to be a shell  script  is  exe-
     cuted  (see  COMMAND  EXECUTION under bash(1)),  rbash turns
     off any restrictions in the shell  spawned  to  execute  the
     script.

BUG REPORTS
     If you find a bug in bash, you should report it.  But first,
     you  should  make  sure that it really is a bug, and that it
     appears in the latest version of bash.  The  latest  version
     is always available from ftp://ftp.gnu.org/pub/bash/.

     Once you have determined that a bug actually exists, use the
     bashbug  command to submit a bug report.  If you have a fix,
     you are encouraged to mail that as  well!   Suggestions  and
     `philosophical'   bug   reports   may   be  mailed  to  bug-
     bash@gnu.org or posted to the Usenet newsgroup gnu.bash.bug.
